Default Mars Lander 3D printable

It took about 2 months of work, but I have completed a printable Mars Lander:

Many thanks to member SCIGS30, whose excellent photos of his Estes Mars Lander build on this forum helped me with details and measurements.

Enjoy !

That's cool, may be a candidate for 18mm D motors.

The original is a definite candidate for 18mm APCP SU/RMS motors.
For this one it would be a must.
No way on a wimpy C6-3 !

The internal diameter of the lower core section is equivalent to a BT-60 tube, and I made sure that there is enough room for motors up to 95mm in length.

Wow, this looks really nice!

What is the mass of the shroud (ascent stage) with nose cone? And mass of the cylindrical lower body (no legs or anything else). I do not mean the whole model, but the masses of the pieces.

I already had planned to build a Mars Lander this winter. Actually got a Semroc/eRockets kit, started on the paper shroud but it was lopsided (my fault) and for various reasons I was seriously thinking about having a wooden pattern made to vac-form the shroud (sacrificing the embossed detail). This seems MUCH better.

The ascent stage with nose cone and nose cone base is 81 grams. That includes an internal BT-60 sized core tube that is the parachute compartment.

The descent stage alone (without lower core or legs) is 42 grams.

These numbers are for parts printed in MARS brand white PLA (appropriate, huh?).

Hey George ! You and I met sometime back in the 90s, I believe. I was a member of the Superstition Spacemodeling Society 93 thru 98. Ed LaCroix was a member, too - probably still is.

I would love to send you an entire printed Mars Lander, or parts of it, if you would maybe try to get photos or video of it in flight, and give me feedback on how the design might be improved. I don't get out much to launches anymore, but I enjoy designing and building.

This is just for fun, mind you. I have no intention of selling these. I just like to put stuff out there that can promote the hobby if possible.

Or do you have your own printer now, and are able to print this yourself?

If you just need the outer skin, I could create .stl files to print them single-wall and eliminate the internal stuff which would reduce the weight by more than half.

Wow Greg, what a great offer.

I did go to a number of SSS launches in the 1990's when I'd fly out to visit Ed LaCroix once or twice a year.

I'll get back to you via a PM, I have to get up very early tomorrow so only have time to post this before calling it a night.

Your ML is awesome!

Too bad you won't be selling any kits.

Depending on the price, I would think very hard about buying one.

Once again, awesome!

I told Chris Taylor about this (Chris does NARAMlive.com and RocketryLive.com among other things). He contacted MechG.

Chris printed one and posted a video about it on his "Today's 3D Print" channel.

So neat to see it on a video, parts snapping into place, legs moving, and such.

Really wish that Youtube Videos would show a preview on YORF. Screenshots:

Very cool Greg! I'm curious to know if you fly with the St. Louis Rocketry Association? I would love to see your Lander fly in person.
